Use of the SAR Shadowing Effect for Deforestation Detection with Sentinel-1 Time Series
Remote Sensing, 2018 To detect deforestation using Earth Observation (EO) data, widely used methods are based on the detection of temporal changes in the EO measurements within the deforested patches. In this paper, we introduce a new indicator of deforestation obtained from

Hyperbolicity, shadowing directions and sensitivity analysis of a turbulent three-dimensional flow [PDF]
Journal of Fluid Mechanics, 2017 This paper uses compressible flow simulation to analyse the hyperbolicity, shadowing directions and sensitivities of a weakly turbulent three-dimensional cylinder flow at Reynolds number 525 and Mach number 0.1.

Nonlinear model evaluation: $\iota$ shadowing, probabilistic prediction and weather forecasting [PDF]
, 1998 Physical processes are often modelled using nonlinear dynamical systems. If such models are relevant then they should be capable of demonstrating behaviour observed in the physical process. In this thesis a new measure of model optimality is introduced:

Observation Methods: Learning about Leadership Practice through Shadowing
Journal of Educational, Cultural and Psychological Studies, 2013 It is known that the role of principals is crucially important to school success. It is also known that their work is very demanding and stressful. Can anything be learned about principalship from studying how school leaders spend their time or from ...

A comparison of phonetic convergence in conversational interaction and speech shadowing
J. Phonetics, 2018 Phonetic convergence is a form of variation in speech production in which a talker adopts aspects of another talker’s acoustic–phonetic repertoire. To date, this phenomenon has been investigated in non-interactive laboratory tasks extensively and in ...

On Shadowing the κ-μ Fading Model [PDF]
IEEE Access, 2018 In this paper, we extensively investigate the way in which $\kappa $ - $\mu $ fading channels can be impacted by shadowing. Following from this, a family of shadowed $\kappa $ - $\mu $ fading models are introduced and classified according to whether ...

RSSI-Based Localization Schemes for Wireless Sensor Networks Using Outlier Detection
Journal of Sensor and Actuator Networks, 2021 The received signal strength indicator (RSSI) of RF signals is a cost-effective solution for distance estimation, which makes it a practical choice for localization schemes in wireless sensor networks (WSN).

Double Shadowing the Rician Fading Model
IEEE Wireless Communications Letters, 2019 In this letter, we consider a Rician fading envelope which is impacted by dual shadowing processes. We conveniently refer to this as the double shadowed Rician fading model which can appear in two different formats, each underpinned by a different ...

On the Effect of Shadowing Correlation on Wireless Network Performance [PDF]
IEEE Conference on Computer Communications, 2017 We propose and analyze a new shadowing field model meant to capture spatial correlations. The interference field associated with this new model is compared to that of the widely used independent shadowing model.
